DEVICE FOR THE COMBUSTION OF LIQUID FUEL.

Application filed February 4-, 1922.

To aZZ whom it may concern:

Be it Known that I, SAMUEL Tnoon, a citizen of the United, States, residingat Haysville Borough, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Devices for the Combustion of Liquid Fuel, of which improvement the following is a specification.-

.dy invention relates to improvements in devices for the combustion of liquid fuel. The object is to produce adevice of this cl aracter in which cheapness and simplicity in construction is attained with a maximum degree of efiiciency and economy in operation. I accomplish this object by means of the device hereinafter more specifically described, reference being had to the acconr panying drawings forming part hereof, in which- Fig. 1 is a vertical central section.

F 2 is a section on line 2-2 of Fig. 1.

Referring to said drawings, 1 is a base upon which the fuel combustion unit is supported. The said base is provided with an annular chamber 2, to which gas is carried by the pipe 3, which is connected to an source of gas supply not shown, the walls of said chamber on the inner side thereof being provided with perforations a, for the discharge of gas which, being ignited, produces a flame for the ignition of the fuel drogping through the perforations into the bottom of the troughs and falling from one trough to the other of the combustion unit. The said combustion unit comprises a series of superimposed horizontally disposed annular troughs 5, being comparatively closely associated, forming passages or spaces therebetween. The said troughs are provided with supports or legs 6, projecting from the lower sides thereof. The troughs are also provided with a number of perforations i', formed in the bottom thereof, for the purpose of permitting the liquid fuel, such as oil. to flow through said perforations and fall from the upper trough in a fine stream or film to the trough immediately below. The said base is also provided with a lip 9. which forms a drip pan. for the reception of any fuel that may be falling from the lower most trough. The said drip pan may be provided with a suitable drain pipe controlled'by a drain cool: not shown, for'the purpose of withdrawingthe oil therein when BOROUGH, PENNSYLVANIA, OF ALLEGHENY COUNTY, PENNSYLVANIA, A CORPORA- of the parts of the .ASSIGNOR TO PEOPLES 7 Serial No. 534.244.

desirable. A member 10, hyperboliform in configuration, is centrally supported with said troughs and constitutes means for directing the ascending currents of air across the fuel in the trougl'is for the purpose of promoting combustion of the fuel therein, the said member having wings a, projecting from the sides thereof and forming channels for the guidance of the air which, ascending through said channels shown by the arrows in Fig. 1, passes over the several fuel troughs and in its passage intermingling with the vaporizing gases from the combustion of the liquid fuel. The said member 10, encases or surrounds the fuel supply pipe 11, which is connected to or with any source of fuel supply not shown, the said fuel supply being as a matter of course at a plane above the top of the combustion unit. The said pipe 11, projects through said member 10, and is screw-threaded upon its upper end upon which a nut 12, is secured for the purpose of holding the several parts of the structure firmly together, a nut being on the lower end of the pipe against which the air conducting means is forced. This is the only fastening device necessary to secure all structure firmly together. The top or upper end of the structure is provided with a cap 13, the function of which is to prevent the air ascending vertically centrally of the device and to cause the same to traverse the various troughs as shown in the drawing.

It is noted that the outer edges of the several fuel troughs are inclined on an acute angle, for the purpose of directing the flame arising from the combustion of the liquid fuel in a transverse direction, making substantially a cylindrical column of flame.

Having described my invention, what I claim and desire to secure by Letters Patent 1s 1. In an apparatus for the combustion of liquid fuel, the combination of a base. a series of superimposed cylindrically disposed troughs adapted to contain liquid fuel, the said troughs having perforations in the bottom whereby the fuel. is adapted to drop from one trough to the trough immediately below, a drip pan arranged below the lowermost of said troughs, a cap closing the passage above said troughs, and means for dirooting the streams of ascending air across and between said troughs the said means including a member hyperho-liforni in coniig' nration supported between said troughs.

2.111 an apparatus for the combustion of liquid fuel, the combination of a base having an aniinlar chamber th e rein, the inner Wall of which is perforated and having a drip ,pan integral therewith, means to convey gas to said annular chamber, a series of superimposed eylindricall} disposed troughs adapted to contain liquid fueh the said mag-11s having perforations in the bottom whereby the fuel is adapted to" drop from one trough to the trough immediately below,

a cap elosingl the passage. above said troiighs means for directing the streams of ascending}; air transversely across and between said troughs, the said means including a member hype'rholi oi rnin, eonfi'g'nration supported between' troughs, h p

In testimony whereof, I have hereunto signed my name in the presence of two subscribing Witnesses.
